The haptic and optical impression of quality is now not great, for the price but absolutely fine (I paid 13,99). It's all there, what you need for mounting (screwdriver, 4 screws for the housing itself, another 4 for securing the notebook etc.). No unnecessary packaging waste. Use now 3 pieces of it in notebooks and all function properly, there are no noticeable loss of speed. It's not just the mentioned manufacturer compatible, I use the parts with SSDs from Samsung / Curcial / Mushkin. For long-term quality I can not say anything, they have only one month in use. The internal built-board is another, as in the picture, but that's for sure with every batch differently.
